Answer:
the equation of the line is:
y = 1/2x + 3/2
Explanation:
given points are:
x1, y1 = -7, -2
x2, y2 = -3, 0
equation of the line is:
y = mx + b
where slope, m = y2 - y1 / x2 - x1
= 0 + 2 / -3 + 7 = 2/4 = 1/2
let's take x1, y1 as x, y co - ordinates to find the value of constant, b
-2 = 1/2(-7) + b
-2 = -7/2 + b
b = -2 + 7/2 = -4 + 7 / 2 = 3/2
thus, the equation of the line is:
y = 1/2x + 3/2
